Sleep Detection
Overview
The objective of sleep detection is to identify periods of sustained sleep over the course of several days or weeks. The de facto standard for long-term, ambulatory sleep detection is actigraphy, which is a method of monitoring gross motor activity using an accelerometer. However, actigraphy is not a reliable method for sleep detection as it employs very simple heuristics to determine sleep. Often actigraphy can misclassify periods of inactivity or even not-worn as detected sleep.
